Well, not full fledged plans, but I have the working drawings. I
mentioned that my dad and I are building this together... My dad was an
ME before he retired, so his drawings are better than some purchased
plans. However, they don't cover the entire construction...we made more
than a couple of decisions, on the fly.

Is it better to have a centralized stepper driver "box" or would it make
more sense (separate boards for each axis) to mount each board near the
motor itself? Seems like it'd reduce the amount of wiring, a LOT.
Though it would run the parallel port's signal through a potentialy
noisy environment... I can see both sides.

I have a laptop 5V PS that I'm using to test the stepper board...not
sure how stable the power is, though...and I just sold a dual trace
scope on eBay! Oh well, didn't plan ahead.
